This continuation-in-part application claims priority of Utility patent application Ser. No. 11/595,124 filed Nov. 9, 2006 which claims priority to Provisional Application No. 60/735,030 filed on Nov. 9, 2005, the contents of both applications are hereby incorporated by reference in their entirety.
This invention relates to buses and more particularly to several improved constructions for buses.
A typical bus provides an elongate skeletal construction forming a front end with the windshield for viewing the road, two sidewalls, and a rear end for housing the engine. At an upper corner of the windshield in the front end is displayed a destination sign instructing oncoming passengers of the route number and final destination of the bus. During humid or frigid temperatures, the destination sign is subject to fog or frost which diminishes the visibility of the sign to waiting passengers.
Another feature of existing bus construction is that the sidewalls of the bus are parallel and the front access door has sliding panels that open in the line of site of the side rearview mirror. These panels obstruct the vision of the bus driver for viewing potential passengers leaving or approaching the bus from the rear direction. Further the combination of the door entry and the sidewall being perpendicular to the front of the bus makes entry of the bus by a handicapped person in a wheelchair, a walker, or a small motorized chair from entering the bus.
In another feature offered by the current bus construction is a planar wall formed by the sidewalls of the bus for use for advertising. Generally, the advertising is only attached on the space not occupied by windows. However, screen advertisement is now available which also covers the windows but allow for passengers to view the outside. The disadvantage of this advertising scheme is that the amount of advertising is limited and must be physically installed and later removed in order to apply another advertisement on the sidewall. Further the screened advertisement placed over the windows minimized the viewing pleasure of the passengers in the bus. Although viewing through the screened advertisement is possible, the view is distorted.
Prior bus roof constructions typically included a thin outer roof skin and many reinforcement structures generally positioned longitudinally down the length of the bus and perpendicularly across the width of the bus to provide the structural stiffness required. Since the outer roof skin was thin and provided little structural support, the longitudinal and lateral reinforcements had to be positioned relatively close to one another and required numerous separate pieces connected together. Where bus roof vents were required, additional reinforcements were needed to frame the opening and connect to the other adjacent reinforcements. The numerous interconnected reinforcements add cost in materials, manufacturing and assembly of the bus.
It is the intent of this invention to address the aforementioned concerns.
In one aspect of the invention an improved designation sign is provided that is positioned and configured for maintaining the sign free from frost and moisture when the vehicle is in use.
In another aspect of the invention, an improved bus construction is provided that facilitates entry into the bus by wheelchair bound passengers and prevents visual obstruction for the driver when the front door is open. One means for accomplishing these advantages includes an inwardly tapered front side having the front door assembly disposed therein. The front door assembly includes a pair of panels that move between an open position and a closed position and are configured for moving out of a driver's line of vision to the side mirror when the pair of panels are in the opened position.
In yet another aspect of the invention an improvement to the bus construction includes an advertising presentation positioned along an upper portion of the sidewalls and visible through the panes of glass of the window assemblies when the window is in the closed position.
In another example of the invention, a bus roof support structure includes a multi-layer structural roof skin and roof reinforcement members angularly positioned with respect to one another and extending radially outward from one or more joints. The roof reinforcement members are connected to the roof panel.
Other applications of the present invention will become apparent to those skilled in the art when the following description of the best mode contemplated for practicing the invention is read in conjunction with the accompanying drawings.
The description herein makes reference to the accompanying drawings wherein like reference numerals refer to like parts throughout the several views, and wherein:
Referring to the
Main body structure 16 comprises a plurality of welded together metallic members and, specifically, includes a roof longitudinal tubular member 70, an upper longitudinal tubular member 72, a waist longitudinal tubular member 74, an angle longitudinal member 76, a lower longitudinal, tubular member 78, vertical tubular pillars 80, and a plurality of diagonal tubular truss members 82 arranged in crossed fashion.
Roof member 70 is arranged in a canted fashion and the upper ends 80a of pillars 80 are beveled and welded to a canted, lower side face 22a of the roof member. The lower ends 80b of the pillars are beveled and secured to the inboard face 74a of waist member 74 and a reinforcing gusset 83 is weldingly secured between the outboard face of each pillar and the upper face of the waist member 74.
Upper tubular member 72 is constituted by a plurality of tubular member sections 72a extending between respective adjacent pillars 80.
Truss members 82 extend in cross fashion between waist member 74 and lower member 78.
Main body structure 16 further includes an inner skin member 84 and an outer skin member 86.
Inner skin 84 has a planar, lower main body portion 84a and an upper portion 84b offset outboard with respect to lower portion 84a. Upper portion 84b includes an offset section 84c, a vertical section 84d, an upper horizontal section 84e, and a downturned lip section 84f.
Outer skin 86 includes a main body planar portion 86a and an offset upper edge portion 86b. Offset upper edge portion 86b includes an inwardly and upwardly angled section 86c terminating in a vertical lip section 86d. Angled section 86c is positioned against gussets 83 with lip section 86d extending upwardly in general alignment with inner skin lip section 84f.
The roof and side window construction 18 of the bus is best seen in
The roof and side window construction 18 includes a plurality of window assembles 26 arranged in side-by-side relation along each side of the vehicle and each including a glass pane 28, a frame 30, and a pivot member 32.
Each pane 28 has a curved configuration conforming to the desired cross-sectional configuration of the bus.
Each frame 30 has a U-shaped configuration and is adhesively secured to the inner face 28a of the pane with the individual frame sections 30a, 30b, and 30c inwardly spaced relative to the respect side edges 28b, 28c, and 28d of the pane and the top of the frame en masse spaced significantly downwardly down from the top edge 28e of the pane.
Each pivot member 32 includes a lower socket portion 32a fitted over the upper edge 28e of the respective pane and adhesively secured to the pane and an upper arcuate pivot portion 32b.
Successive pivot members 32 are pivotally received in an aluminum extrusion member 36 extending along each upper side of the bus. Each extrusion member 36 includes an upper socket portion 36a receiving a roof panel 38 forming the roof of the bus, a socket portion 36b pivotally receiving the pivot members 32, and an arcuate connector portion 36c. Roof panel 38 has a laminated construction including a central balsa wood core 38a and fiberglass upper and lower sheets 38b. Socket portion 36b defines an arcuate socket 36d receiving the pivot portion 32b of each pivot member 32, whereby the successive window assemblies are pivotally mounted along each side of the bus and may move selectively between lowered or closed positions and raised or open positions.
In their lowered position, a side edge 28b of the pane of one glass assembly is positioned immediately adjacent the side edge 28d of an adjacent window assembly with the lower frame member 30b nesting within an immediately above horizontal section 84e of inner skin 84, side frame members 30a and 30c of adjacent window assemblies positioned in flanking but somewhat outboard relation to respective pillars 80, and the side edge portions 28f of the panes 28 outboard of the respective frame members 30a/30c positioned proximate the outboard face 80a of the pillar with seals 42 (
With the window assemblies in their closed positions, the top of each window assembly frame 30 is positioned proximate a tubular section 72a and the lower edge portion 28g of each glass pane below the lower frame member 30b may rest against the upper edge 86d of outer skin 86 with a seal 50, carried either by the glass or by the skin, interposed between the glass and the skin. The glass assemblies may be moveable between their open and closed positions either manually or with the aid of strut assist devices (not shown). The described window construction also allows ready access to a compartment 49 over the windows within the extrusion member 36, allowing access to wire harnesses, compressed air plumbing, and other accessory components positioned within the extrusion member.
